Contraceptive coil can be found in two different kinds – copper-based intrauterine devices (IUD) and hormonal intrauterine devices, also called IUS – intrauterine system. Both of them are made from plastic, either "coated" with hormones or copper. Both methods of IUD contraception will be inserted into the uterus for complete protection against pregnancy for a long time. This protection usually lasts for around 5 to 10 years. However, they do not provide protection against sexually transmitted infections.
IUD is a small device in T-shape form that produces copper ions which killthe sperm. The coilworks by preventing sperm from getting into the ovaries by stopping fertilised egg from implanting in the uterus. Various threads are attached to the coil that makes it quite easy to check that it is in its proper place.The coil may also be used for emergency contraception when the coil insertion procedure is done within 5 days after you have had unprotected sex.
Copper coil usually works for 10 years and you will have to go for regular check-ups to ensure the coil is still in its place. Contraception with coil is nearly 98-99% effective for the first 5 years.
The physical appearance of hormonal coil insertionis somewhat similar to the copper-based option. It is exactly the same to the T-shaped plastic device, except it is“coated” with hormones.
